Guicheon is an old teahouse in an Insadong alley, known for traditional tea. It brews jujube tea, ssanghwa tea, quince tea, and omija tea by hand, and serves hangwa with each tea order. The poet Cheon Sang-byeong's nephew now runs the place, and poems, writings, and small objects remain throughout the interior. The old dabang-style atmosphere stays quiet on weekends.
